We absolutely do give kudos to the mathematician(s) behind the CryptoNote cryptography (and who we'd love to have on the Monero Research Lab panel), and credit does also have to go to the developer(s) who produces the CryptoNote reference code in the 7 months at the end of 2013 / beginning of 2014. If the original Bytecoin developers were involved in the creation of the reference code, then those kudos and credit extend to them up to that point, but we absolutely do not give credit for their attempt to fleece the cryptocurrency community.
